Step 1: Carbon was mentioned as the central atom.
Step 2: The total number of valence electrons present in COF2 is:
Group Valence Electrons
C. 4A 1 × 4 e– = 4 e–
F 7A 2 × 7 e– = 14 e–
O 6A 1 × 6 e– = 6 e–
Total: 24 valence e–
Step 3:Let’s first connect each atom according to their bonding preferences.
Halogens such as fluorine only forms 1 bond and oxygen prefers to form 2 bonds.
For COF2 draw an appropriate Lewis structure (carbon is the central atom).
